In vitro fertilization and embryo transfer programme in Ljubljana

Results of the IVF-ET programme from June 1983 to July 1984 are presented. The procedure was performed in 98 women in 127 cycles. Six normally ongoing clinical pregnancies, three early spontaneous abortions and six biochemical pregnancies were achieved. The laparoscopic techniques of oocyte retrieval were used. Ovulation was first stimulated by clomiphene citrate and later on by gonadotropins only. Comparison of these two regimens showed gonadotropin stimulation to be more effective than clomiphene stimulation, considering the respective transfer rate of 73.3% (gonadotropins) and 18.8% (clomiphene).
